To all whom t may concern:

Be it known that l, SIDNEY T. Bo'rrnnrmLn, a citizen of the United States, residing at Cleveland, in the county ofCuyahoga and .State of Ohio, have invented 'new and useof this lrind embodying an aluminum' or,A

other metallic casing comprising rim and tread members Which are detachably conf nected together and a pneumatic inner tire arranged Within the casing so that the tire is puncture-prooiI and yet secures all the properties and resistance qualities of Van ordinary rubber tire.

rlhe invention consists in the construction, combination, and arrangement of devices, hereinafter described and claimed. A

Figure l is a transverse sectional' view of a tire constructed and arranged in accordance with my invention.

Fig. 2 is a perspective vieuv of the rim member.

Fig. 3 is a similar view of the tread member.

F ig. fl is a transverse sectional view of a modied form of my improved tire.

Fig. 5 is a detail longitudinal sectional view of the same.

Referring to the form of my invention shown in Figs. l, 2, and 8, a Wooden rim is indicated at l. rlhe casing of the tire comprises a rim member 2 which is secured on the periphery of the rim and a tread inember 3 Which is detachably secured to the rim member. Each member of the casing is made of aluminum or other suitable metal. rlie rim member 2 forms nearly a complete circle in cross section, is open at its outer side as at et and is provided at the edges of its side Walls with clencher flanges The tread member 3 is "arranged to be fitted in and to project outwardly from the opening 4 of the rim member, and is provided with clencher flanges 6 to engage the clencher flanges 5 and thereby detachably secure the members 2, 3, together.

A tread 7 of rubber or other suitable material is secured on the outer side of the tread member and in practice is about an Specification oi Letters Patent.

inch hier and is of Sniagbie Width. The

the rim member. An inner pneumatic tire 9 isarranged in the casing and is supplied with compressed air through a valve l0 by usual construction. The aluminum or other metal of which the casing members are constructed renders the casing flexible so that it yields to shocks and then reassumes its normal shapeand coacts with the inner .pneumatic tire 9, to provide la tire, which While puncture proof, has all the properties and advantages of an ordinary rubber tire.

In the modified form of my invention, the rim member is indicated at 2a provided with' the clencher flanges 5a. The tread member 3 is made of rubber and fabric and is prolvided With transversely arranged steel spring ribs l1, Which in practice are about an inch apart and are provided at their ends With `clencher flanges l2 for engagement with the clencher flanges 5a of the rim f member 2 of the casing. The tread 7a is similar to the tread in the form of the invention shown in Figs. l, 2, and 3. An inner pneumatic tire 9a is placed in the casing formed by the members 2 and 3 as shown. Y

Having described the invention, What is 'claimed is:

A tire comprising a rim member constructed to be substantially circular in cross section With its two edge portions inclined toward each other but spaced apart to form an annular slot, a clencher flange formed integral With each edge portion and lying parallel thereto, a. metallic annular tread member closing said/slot and having its edge portions bent/into clencher flanges arranged at an angle to each other and the bodyvof the member and having slidable locking engagement with said first men-l tioned flanges and a resilient tread element 'mounted upon said tread member and having parallel sides spa-ced from said llanges which lie at an angle to the sides.

In testimony whereof l allix my signature in presence oftwo Witnesses.
